Content assist doesn't work when an entity alias is not preceded by whitespace
------------------------------------------------------------------------------
Key: HBX-895
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-895
Project: Hibernate Tools
Type: Bug
Versions: 3.2beta8
Reporter: Joseph Marques
In an HQL editor:
If I type - "count(col." - and press ctrl+space, I don't get the content assist for col
If I type - "count( col." - and press ctrl+space, I do
Similarly,
If I type - "select a,b." - and press ctrl+space, I don't get the content assist for b
If I type - "select a, b." - and press ctrl+space, I do
It's pretty clear that the lexing is a little bit too tight here, and that for better usability it should be relaxed. The second case isn't as big a deal as the first (because I don't know a single person that doesn't comma-space delimit the select clause, but I'm thinking that some people that don't realize that they have to put a space in front of it might think that the tools simply can't auto-complete inside functions.

[Hibernate-JIRA] Created: (HHH-3119) LazyInitializationException from 3.2.4+ onward

LazyInitializationException from 3.2.4+ onward
----------------------------------------------
Key: HHH-3119
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3119
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.6, 3.2.5, 3.2.4.sp1, 3.2.4
Reporter: Nick de Graeve
Priority: Blocker
We used to run JBoss 4.0.4.GA and we included Hibernate 3.2.0CR2 ourselves. Now we migrated to JBoss 4.2.2.GA and in that one Hibernate 3.2.4.sp1 is included by default.
Unfortunately, we're getting LazyInitializationException when the object graph is more than 2 levels deep.
E.g. RtTask --[OK]--> Priority --[FAIL]--> DictionaryEntry
We haven't changed anything to our beans or configuration files.
I did find out that v.3.2.4 is the first version that throws the exception.

Hibernate: insert into B (aId, cId, id) values (?, ?, ?)
Hibernate: select a0_.id as id0_0_ from A a0_ where a0_.id=?
Hibernate: select bs0_.aId as aId1_, bs0_.id as id1_, bs0_.cId as cId1_, bs0_.id as id1_0_, bs0_.aId as aId1_0_, bs0_.cId as cId1_0_ from B bs0_ where bs0_.aId=?
I've been having a confusing problem shown above, whereby A has a Map of Bs indexed using the id from an association with C. This Map is inversely mapped for A and with 'Cascade Delete Orphan'. In the second opened session above, where B is removed from A's Map and thus orphaned, B will not be deleted. I have observed B is only deleted if I either set 'lazy="false"' for A's Map or make an interaction with A's Map in the code (before B's removal) like 'a.getBs().get(cId)'. I suspect the lazy intializer is not initializing correctly in the above scenario.
The above scenario does not happen if A's Map is not inversely mapped but B's many-to-one with A is.
Can somebody shed some light on whether this is me using Hibernate incorrectly or is a bug?

[Hibernate-JIRA] Created: (HHH-2881) PersistantBag.initializeFromCache can be intercepted by CollectionLoadContext.getLoadingCollection and so corrupt the collection
by Pavol Zibrita (JIRA)
PersistantBag.initializeFromCache can be intercepted by CollectionLoadContext.getLoadingCollection and so corrupt the collection
--------------------------------------------------------------------------------------------------------------------------------
Key: HHH-2881
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2881
Project: Hibernate3
Issue Type: Bug
Environment: Hibernate Entity Manager 3.3.1 GA, oracle,
Reporter: Pavol Zibrita
It can occur that while PersistenBag.initializeFromCache is called to populate the collection from cache, the collection is populated also from CollectionLoadContext.getLoadingCollection, and so, the collection is filled with more data than needed. As the initializeFromCache uses direct access to the property this.bag, it will continue loading the collection. Here is the stack trace of what happens:

//some stack before, uninportant
Small fix to the PersistantBag has resolved this issue, however I cannot tell if it is correct by some hibernate principles:
public void initializeFromCache(CollectionPersister persister, Serializable disassembled, Object owner)
throws HibernateException {
Serializable[] array = (Serializable[]) disassembled;
int size = array.length;
List<Object> elements = new ArrayList<Object>(size);
for ( int i = 0; i < size; i++ ) {
Object element = persister.getElementType().assemble( array[i], getSession(), owner );
if ( element!=null ) {
elements.add( element );
}
}
beforeInitialize( persister, size );
for ( Object element : elements ) {
this.bag.add( element );
}
}
Difference is, before the this.bag.add(element) was called in first cycle, where the line of getting the element could cause reinitializing the collection and filling it up. There are various possibilities how to fix the problem, but I don't know if the fix is at the right place!

[Hibernate-JIRA] Created: (HHH-3046) Merge fails on complicated data structure because of cycle references

Merge fails on complicated data structure because of cycle references
---------------------------------------------------------------------
Key: HHH-3046

On complicated object structure, hibernate was unable to merge it correctly because of attaching ID's to the new objects in the tree of the persistent entity. Hibernate cannot cope with cyclic references in this case and it fails with:

[Hibernate-JIRA] Created: (ANN-698) @Transient property leads to org.hibernate.AnnotationException: Property has an unbound type
by Sebastian Baltes (JIRA)
@Transient property leads to org.hibernate.AnnotationException: Property has an unbound type
--------------------------------------------------------------------------------------------
Key: ANN-698
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-698
Project: Hibernate Annotations
Issue Type: Bug
Affects Versions: 3.3.0.ga
Environment: hibernate3.jar: 3.2.5.ga
hibernate-annotations.jar: 3.3.0.GA
hibernate-commons-annotations.jar: 3.0.0.GA
hibernate-validator.jar: 3.0.0.GA
MySQL
Reporter: Sebastian Baltes
Attachments: log.txt
Transient fields are not ignored in Hibernate. I got an "Property has an unbound type" exception and found no workaround.
Entity:
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Transient;
@Entity
public class Dummy<K> {
@Id
private Long id;
@Transient
transient private K dummyField;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public K getDummyField() {
return dummyField;
}
public void setDummyField(K dummyField) {
this.dummyField = dummyField;
}
}
Test Code:
EntityManager em = EntityManagerSingleton.get();
EntityTransaction tx = em.getTransaction();
tx.begin();
Dummy a = new Dummy();
em.persist(a);
tx.commit();
